This article uses a unique longitudinal dataset based on administrative data from the National Technical Institute for the Deaf (NTID) linked to Social Security Administration (SSA) microdata to conduct a case study of Supplemental Security Income (SSI) children who applied for postsecondary education at NTID. The authors estimate the likelihood that SSI children who apply to NTID will eventually graduate relative to other hearing impaired applicants, as well as the influence of graduation from NTID on participation in the SSI program as adults and later success in the labor market. Findings indicate that SSI children are substantially less likely to graduate from NTID than their fellow deaf students who did not participate in the SSI program as children, but that those who do graduate spend less time in the SSI adult program and have higher age-earnings profiles than those who do not graduate.
